About the eZV-440

The eZV-440 and eZVP-440 controllers are native BACnet controllers optimized for fan coil

applications. It features line voltage power input with a built-in 24 VAC inverter and line voltage

rated relays eliminating the need for a local control transformer or external relays to switch the fan.

The controller is also designed to be compatible with Delta Controls’ eZNS and DNS-24L network

sensors.

The eZV-440 comes preloaded with algorithms which you configure using a configuration graphic

to match your site’s needs. There are 2 types of eZV-440 controllers: both the configurable (eZV)

and programmable (eZVP) models use the configuration graphic for setup but only the

programmable controller allows you to overwrite the default sequences with General Control

Language (GCL) programming.

You can use ORCAview 3.40R3 and higher or enteliWEB 4.1 and higher to access the

configuration graphic.

About This Guide

This application guide introduces the controller and describes the differences between the

configurable and programmable models. The guide also shows you how to use the configuration

graphic in ORCAview 3.40 R3 and higher to set up your eZV-440 controller. The product name

eZV-440 in this guide refers to both the configurable and programmable models unless stated

otherwise.

The ORCAview configuration graphic version referenced in this guide is B-169041.1.

For help with the eZV-440 configuration page in enteliWEB 4.3 and higher, go to the online help in

enteliWEB. enteliWEB users require the applicable object permissions to change the settings on

the configuration page.

The installation guide for the eZV-440 can be found on the eZV-440 product web page on

the Delta Controls Support web site.
